' is Claims. (01. 129-41) 7 This invention relates to an improvement in binders designed for use with loose leaves and also with catalogs, bulletins, pamphlets, or other material. vThe binder provides a simple, compact, easily handled, and effective enclosure for the material contained therein. and yet such material is accessible for full and complete as well as easy and convenient inspection at all times- Further, the leaves or other material may be readily placed in or removed from the binder.

One of the objects of the invention is to'provide a binder whose'capacity for containing and holding sheets, catalogs, bulletins, or other papers, may be quickly and easily varied. :Whereloose leaves are secured in the binder they areeffectively and securely clamped in position and this notwithstanding that the number of such leaves may be widely varied. Catalogs, bulletins, or the like, contained in the binder are instantly available for complete and convenient inspection. Along with these advantages the binder is so constructed as to be susceptible of convenient and'economical manufacture and its parts are so constituted and and combination of parts which will-be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is a View partly in end elevation and partly in transverse vertical section showing a binder embodying the present invention employed for containing both loose, leaves and other papers such as catalogs, pamphlets, bulletins, or the like;

' being broken away for the sake of illustration;

Figure 4' is a detail view partly in elevation and partly in vertical section showing one of the looks or clamps employed for securing one of the loose leaf clamping bars in positionon the bands connecting the cover members of the binder;

ing a modified construction;

Figure 8 is a detail sectional view on line 8-8 of Figure 7; and 1 Figure 9 is a perspective view illustrating one vof the leaf clamping strips employed with the binder shown in Figure 7.

Referring to the drawings, and more particularly to Figures 1 to 6, inclusive, it will be seen that the binder illustrated in this embodiment of the invention comprises a pair of cover members designated at I and 2. Except as will be pointed out hereinafter, the cover members I and 2 may be of any suitable construction and as usual :consists of one or more plies of cardboard and asuitable covering material such as leather or the like. .Integral with the covering materialof the cover member I is a flexible backing 3 provided with a tapering or somewhat reduced extension t. The cover member 2 has a pocket 5 therein opening throughout practically the entire extent of its rear edge but closed at the forward edge of the cover member except for a narrow slot-like aperture 6. A reinforcing metal strip 7 is suitably secured to the free edge of the extension 4 of the flexible backing. Any suitable means may be employed for appropriately securing this reinforcing strip to the extension 4 and in the construction illustrated eyelets or rivets designated at 8 are contemplated. A strapll is provided and has one end riveted or otherwise suitably connected as indicated at ID to the extension 4 and also to the central portion of the reinforcing strip 7.; This strap is extended through the pocket 5 and out through the slotlike aperture 6 thereof. When not employed for adjusting the extensicnfi, and; consequently also the flexible backing of the binder, its loose end may be confined under a spring clasp H.

' The binder is equipped with anydesired number of leaf holding bands designated at l2. In

the embodiment shown in Figures 1 to 6, two such bands are provided. Each band has one end fastened as by means of an eyelet 13 to the reinforcing strip and to the extension 4 of the flexible backing 3. Each band It is extended from itspoint of attachment to the strip 1 and extension 4 rearwardly through the pocket 5 and thence out through registering openings or slots designated at l4 and I5 provided respectively in the cover member 2 and in the fiat attaching portion l6 of a sleeve-like roll or bead IT.

The end of each band opposite to that fastened to the strip 1 is bent back upon itself as indicated at H! and into the formation of a hinge collar 20. The end portion |8 is suitably secured as by means of an eyelet or rivet to the part of the band whichit engages. The hinge collars 20 at the ends of the bands are releasably and pivotally interfitted with the. cover member this being effected by positioning the attaching collars 20 in notches 2| formed in a hinge sleeve 22 and inserting a retaining pin 23 through the hinge sleeve and through the attaching collars. The hinge sleeve 22 has integral therewith an attaching strip or plate 24 which rests flatly against the inner edge portion of the cover and is riveted or secured thereto by eyelets or in any other suitable fashion. One end of the elongated retaining pin 23 is bent at an angle as indicated at 25 to provide a handle whereby to facilitate its insertion and removal.

The leaf holding bands |2 are constructed of spring steel or other resilient metal and when organized with the binder structure in the manner herein described are highly effective to engage notches formed in leaves, catalogs, or other papers, and extending out through the edges thereof for appropriately securing such papers in the binder and yet are also effective to allow of convenient and complete and full display of or access to the catalogs, pamphlets, leaves, or the like.

For the purpose of clamping loose leaves securely within the binder and in proper relation to said leaf holding band and to the other elements thereof cooperable leaf clamping bars 30 and 3| are provided and have openings 32 therein through which the leaf holding bands l2 freely extend. The leaf clamping bar 30 has bearing strips 33 riveted or otherwise suitably secured thereto adjacent its ends and pivotally receiving portions of the elongated retaining pins 23 projecting beyond the hinge sleeve 33 so that this leaf clamping bar 30 is pivotally interconnected with the cover member The other leaf clamping bar 3| is freely slidable along the leaf holding bands I2 but may be securely fastened thereto in any adjustment by means of locking devices 35 mounted on the leaf clamping bar 3| and cooperable with the bands l2. There is one such locking device 35 for each leaf holding band.

Referring now to Figures 4 and 5 it will be seen that the locking devices have a common mounting strip 36 riveted or otherwise suitably secured as at 31 to the leaf clamping bar 3|. Adjacent each leaf holding band l2 a stud 38 is threaded into the mounting strip 36. A clamping lever 39 has an opening 40 loosely receiving the stud 38 but .thehead of the stud provides a fulcrum engageable with the margins of the upper portion of the opening '49 and on which the clamping lever 39 is rockable. The band engaging portion of each clamping lever is designated at 4|. The opposite end portion of each of these levers is formed on its underside with a semi-circular notch 42. Rotatable in this notch 42 is a semicylindrical .camming member 43 formed as an integral lateral projection of a finger piece 44.

Adjacent its notch 42 each lever 39 is cut away to provide clearance in which the finger piece 44 may operate. When the finger pieces 44 are pressed down to the full line position shown in Figure 4, the camniing member 43 is rocking around to the position shown, thereby raising the adjacent end of the lever 39, rocking the lever about its fulcrum provided by the head of the stud 38, and causing the portion 4| thereof to have clamping frictional or securing engagement with the band I2 which is then confined between such portion 4| and the opposed portion of the strip 36. Swinging of the finger piece 44 from the full line position of Figure 4 to the dotted line position thereof brings the flat side of the camming member 43 adjacent the strip 36 and allows the camming member to be accommodated Within the notch 42 throughout its extent. This allows the end 4| of the lever to move away from the band l2 thereby disconnecting the leaf clamping bar 3| from the bands and allowing free adjustment of the same along the bands |2.

In Figures 1 and 2 the loose leaves are designated at L and are shown as having notches N extending out through the inner edges thereof and through which the leaf holding bands l2 extend. The leaf clamping bar 30 engages one side of the leaves L whereas the opposite side is engaged by the clamping bar 3|, the two clamping bars 30 and 3| cooperating to firmly clamp the notched ends of the leaves in position on the bands l2. The clamping bar 3| is held in position to effect this clamping of the leaves by virtue of the action of the locking devices 35 which clamp or lock the bar 3| to the bands |2 in the proper position.

The cover members may be adjusted toward and away from each other to provide the desired amount of flexible backing 3 between them by releasing the strap 9 from its clasp II and pulling the cover member 2 out along the extension 4 of the backing 3. In this way space may be provided on the bands |2 between the clamping bar 3| and the cover member 2 to allow of the engagement of catalogs, bulletins or pamphlets with the leaf holding bands l2 and provide for their proper retention within the binder. Such bulletins or the like may be readily displayed by opening up the binder as shown in Figure 2 and then opening up the bulletins. The extension of the bands l2 over the roll I! causes them to bow or flex upwardly and this aids in the proper display of the pamphlets, bulletins, or the like.

To close the binder the strap 9 is pulled to draw the flexible backing taut and to cause the clamping bar 3| and the locking devices 35 of the clamping bar 3| to compress the inner edges of the catalogs, pamphets, or the like, between bar 3| and the roll or bead H, the cover members and 2, being disposed in parallelism as shown in Figure 1. The provision of the roll or bead I1 and of the hinge roll 22 together with the pivotal interconnection between the bands !2 and the hinge roll 22 precludes excessive or sharp bending of the leaf holding bands. The binder may be opened to afford access to or inspection of the loose leaves, catalogs or pamphlets by releasing the strap 9, swinging the cover members to open position, and allowing the leaf holding bands to flex or bow upwardly as shown in Figure 2.

The form of the invention shown in Figures 6, 7 and 8 is, in most respects, identical with that just described in that it has the cover members and 2, the flexible backing 3 with its extension 4, the reinforcing strip 1, tsarp 9, clasp roll 22. and a set screw 56.

holding bands l2, sleeve-like'rolls l I and22 with which the bands l2'are organized inthe manner previously described, and leaf clamping bars 30 and 3 I. In fact, the only difference between this form: of the invention and that previously described, resides in the manner of adjustably securing the "leaf clamping bar 3| in position. In lieu of'the locking-devices 35 a third band 501s provided and has one end connected to the cen-'- tral portion of the clamping bar 3| and its-other end adjustably secured by a suitable fastening device 5| to the .covermember Lthe intermediate portion of the third band passingthrough a slot52 invthe leaf clamping bar 30. While the particularmanner of fastening one end of the band 50 to the bar 3| maybe varied, preferably the band has at one end an eye or hinge co1lar 53 which pivotally andreleasably embraces or receives an elongated securing pin 54, the pin passingthrough strap-like bearings 55 secured to the bar 3| andprojecting from one face thereof; The fastening device 5| may also take a variety of forms but-in the particular construe tionsillustrated consists of a guide 58 suitably fastened to the attaching portion 24 of the hinge The band 50 passes through the guide freely but may be held in position by tightening up on the set screwiii to cause the screw" to engage the band and clamp said band between itself and. the attaching portion 24. A finger ring 5! may be secured to the free end of the band 5! to facilitate manipulation thereof.

In this form of the invention the action of the clamping bars 3!] and 3! in holding the leaves is regulated by the third band 50. Obviously, by releasing the set screw and moving the band 5E3 in one direction or the other the bar 3i can be moved to have clamping engagement with the leavesor to release them. When the band 50 is pulled to cause the bar 3| to have clamping engagement withthe leaves such clamp,-

7 ing action may be maintained by tightening up on the set screw 56.
